CO
Command

Michael J. Mefford 1987/No. 21 (Utilities)


Purpose: Copies, moves, or deletes files individually or in tagged
groups from directory listings sorted by name, extension, size, or date.

Format: CO [d:][\directory][/E][/S][/D][/T][/O]

Remarks: Entered without any of its optional parameters and switches,
CO presents an alphabetized listing of the current directory with a menu of
Function Key commands on the right. The file attributes (Archieve, Hidden,
Read-Only, and System) are shown by the appropriate letters to the right of
each listed file. The Up- and Down-Arrow keys move the file-selection
highlight bar one line at a time. Ctrl-PgUp (^PgUp) and ^PgDn move to the
top and bottom of the current display page (21 files), while PgUp and PgDn
allow you to scoll through the entire directory listing. The Home and End
keys go to the beginning and end of the listing, respectively. Pressing a
letter moves the highlight bar to the first (then subsequent) filename(s)
beginning with that letter. Multiple files are tagged for group copying,
moving, or deleting by pressing the gray plus (+) key; the gray minus (-) key
unmarks a mistagged file.

The optional /E, /S, /D, /T, and /O command-line switches sort the
initial directory listing by Extension, Size, DaTe (/D and /T operate
identically), or by Original DOS order. Once on screen, function keys F7
(Name), F8 (Extension), F9 (Size), and F10 (Date) can be used for subsequent
sorts. F1 initiates the Copy process for the highlighted (or marked)
file(s). F6 toggles the Copy Verify option (comparable to DOS /V). F2 and
F3 are used for Move and Delete. You are prompted for the appropriate
destination for Copy and Move: different drives and paths are supported, as
is the use of the DOS ? and * wildcards. Renaming while copying is
permitted.

When a marked (tagged) file is successfully copied, its marker arrow
is replaced by an asterisk. If a floppy disk becomes filled, CO
automatically attempts to find other marked files that will fit, backup but
will then halt with some file(s) remaining to be copied. Replace the full
diskette with another, hit F1 again, re-enter the correct destination drive,
and the remaining marked files will be copied.

To divide the contents of a directory into two parts, mark and copy
the first set of files, as above, so that all have the "copied" asterisk.
Then press F5 to mark the previously-untagged files and repeat the copying
process for the second group.

Note: CO functions can alternately be performed by Ctrl-letter commands: ^C
(Copy), ^D (Delete), ^M (Move), ^V (Verify), ^N (Name), ^E (Extension), ^S
(Size), and ^T (Date).
